NFL player gives his daughter a pep talk before cancer surgery

This daddy-daughter moment is the most precious thing ever.

Cincinnati Bengals defensive tackle Devon Still is facing a huge battle off the field — his daughter Leah is fighting pediatric cancer. Despite his NFL commitments and the demands of a new season, it's clear Still has done everything he could to be with his daughter.

On Thursday, he posted this adorable Instagram video of a little pep talk he gave Leah in the car on the way to her surgery. It's so adorable, there are no words.

Gah. What a cool dad. What a devastatingly cute little girl. If your heart can handle it, skip over to his Instagram page to see more beautiful shots of the two. Leah was diagnosed with neuroblastoma in June, and after Thursday's surgery, Still's posts seem to be optimistic.
